广东罗浮山省级自然保护区鸟兽多样性及分布特征

The Diversity and Distribution Characteristics of Birds and Mammals in Luofu Mountain Provincial Nature Reserve, Guangdong, China

  • 摘要: 【目的】完善广东罗浮山省级自然保护区野生动物资源数据,了解不同海拔、生境和区域间的鸟兽分布差异,以期为保护区将来的管护和规划提供参考资料。【方法】于2021年8月至2022年6月期间,将保护区按照1 km×1 km网格化,并在此基础上划分为东、西2个样区,布设40台红外相机开展监测工作。【结果】本次监测累计工作11 544 d,获取独立有效照片5 185张,其中兽类照片2 393张,鸟类照片2 730张,两栖类照片1张,干扰照片61张。记录到兽类3目8科12种,鸟类7目14科34种,其中属于国家一级重点保护野生动物的有1种,为小灵猫(Viverricula indica);国家二级重点保护野生动物有8种。相对多度指数最高的兽类是鼬獾(Melogale moschata)(IRA=6.15)、鸟类是白鹇(Lophura nycthemera)(IRA=14.84)。在不同海拔、生境和样区间鸟类物种数及相对多度指数均无差异;不同海拔梯度上兽类物种数和相对多度指数存在差异显著,2个样区间仅兽类相对多度指数存在差异显著。依据监测数据,保护区中存在5种干扰类型分别为:采集者、行走者、家羊、家犬和家猫。【结论】罗浮山保护区内兽类和林下层鸟类资源丰富;由于红外相机监测鸟类的局限性、鸟类自身迁移行为和分布特点,在本次监测中保护区鸟类资源的分布情况并无明显不同;兽类物种数在海拔梯度上的分布类似于中峰分布格局;鼬獾和鼠类在800~1 000 m海拔段活动频繁,是造成兽类相对多度指数在海拔梯度上和样区间显著差异的原因。样区1和2的主要干扰类型以及每种干扰类型对于野生动物的影响程度均不一致。

     

    Abstract: 【Objectives】 To improve the wildlife resource data of Luofu Mountain Provincial Nature Reserve of Guangdong, comprehend the distribution disparities of birds and mammals at different elevations, habitats, and regions, and provide references for the reserve’s future management and planning. 【Methods】 From August 2021 to June 2022, the Nature Reserve was gridded at 1 km×1 km intervals and divided into two sample sections, east and west. Simultaneously, 40 camera traps were deployed for monitoring. 【Results】 During the 11 544 camera days of monitoring, 5 185 independent photographs were taken, including 2 393 photos of mammals, 2 730 photos of birds, 1 photo of amphibians, and 61 shots of interference. We discovered 12 mammal species from 3 orders and eight families and 34 bird species from 7 orders and 14 families. Only Viverricula indica is listed as first-class national protected wildlife, while the additional eight species are listed as second-class national protected wildlife. Melogale moschata (IRA=6.15) and Lophura nycthemera (IRA=14.84) are the mammals and birds with the highest relative abundance index (RAI). The number of bird species and RAI did not differ between elevations, habitats, or sample areas. There were substantial changes in the number of mammal species and RAI at different elevations, with only the RAI of mammals being significantly different between the two sample sites. According to monitoring data, there are five sorts of disturbance in the reserve: collectors, walkers, goats, dogs, and cats. 【Conclusions】 The Luofu Mountain Nature Reserve was abundant in mammals and undergrowth birds. There was no substantial difference in the distribution of birds in the reserve during the monitoring period due to the limits of infrared cameras in monitoring birds and the birds' migration behavior and distribution features. Mammal species distribution along the altitudinal gradient was similar to the pattern of the mid-elevation peak. The RAI of mammals differed significantly between the altitude gradient and the sample areas because Melogale moschata and rodents moved frequently at 800−1 000 m altitude. The main interference types in sample areas 1 and 2 were inconsistent, as was the influence of each on wildlife.
